In this Wednesday, Jan. 8, 2014 photo, patrons tour an ice castle at the base of the Loon Mountain ski resort in Lincoln, N.H. The ice castle begins to grow in the fall when the weather gets below freezing and thousands of icicles are made and harvested then placed around sprinkler heads and sprayed with water. The castle will continue to grow as long as the temperatures stay below freezing. (AP Photo/Jim Cole)

Instead of building the castle, those involved describe the process more like farming. They grow the initial icicles, then they harvest them. After that, they increase the size of some of them using processes that can include using sprinkler heads. And then of course comes the building.

Be sure to catch this cool music video by Lindsey Stirling, too. It was shot inside one of their castles. (Big thanks to NHPR – linked aboved – for getting the video in front of my eyes and ears. The music is pretty great, too. I've already listened to the song twice this morning.)

So have you seen the ice castle? Let us know what it was like in the comments!
